# High Speed Photography Using Arduino

With this device you’ll be able to:
take pictures from anything you can sense or detect:
– movement
– sound
– …
You don’t need to modify your camera or flash for this.
It’s compatible with the old High Voltage flashes and the new TTL ones.

Why I did this project?
A friend of me who’s really passionate about photography showed me some high speed photography examples. And how expensive the equipment you need is.
I said there must be a DIY solution for that and I started tinkering.
We’ve done some experiments and you can see the results in the pictures below.

After following this instructable you’ll be able to make such pictures too!!

What I would do with the zing
If I win the zing laser cutter then my lab is complete, and will I be able to go crazy.
I’ll make: robots, enclosures, front panels, puzzles, build kits, moose heads, etch some cool things
I’ve been waiting a long time to make this instructable so I could join the zing contest and here I’m

## Step 1: Laser Trigger (Light barrier) Sensor

The laser trigger exists of 2 pieces:
-the sensor (this step)
-Laser itself (next step)

See the included pictures for the circuits
You’ll need:

• a phototransistor / photodiode
• just a resistor like 10k

## Step 2: Laser driver

Calculate the resistor you need with the following formula
R = 1.25V / Laser Current in A

You’ll need:

• A led laser diode (ebay)
• LM317
• 1 x Resistor

or you can skip the driver and just use a resistor placed in series with the laser diode

## Step 3: Build the circuits (Arduino)

You can connect everything to an arduino
Or you can make a pcb (see next step) to do the job so you have your arduino free for other projects

connect your lcd to the arduino see the circuit

connect the output of the sensor circuit to the analog pin 0

connect your digital pin 12 to the flash trigger circuit
